Here's a breakdown:
* Consonant sound: The focus is on the sound, not the actual letter. For example, "Peter Piper picked a peck of pickled peppers" uses the "p" sound, even though the word "picked" has a "k" in it.
* Close together: The words need to be relatively close in the sentence or phrase. This is subjective, but generally, they should be within a few words of each other.
* Creates a rhythmic effect: Alliteration often creates a pleasing, rhythmic effect and can make writing more memorable.
Examples:
* She sells seashells by the seashore. (the "s" sound)
* Peter Piper picked a peck of pickled peppers. (the "p" sound)
* Busy as a bee. (the "b" sound)
* The wild waves whipped the wind. (the "w" sound)
Alliteration is often used in poetry, songs, and advertising to create a catchy and memorable effect.
